Joining the striking workers in that aim are about 15 tractors that drove up onto the roadway shortly after the blockades were removed, according to Unifor Local 16-0 president Gary Lynch.

Last week, the Ontario Superior Court issued an order requiring the striking workers to remove their blockade by 4:30 p.m. Saturday, according to a post on Compass Minerals' bargaining website.

Compass Minerals, the company that operates the mine, says the blockade was jeopardizing the safety of workers, contractors and customers.

Lynch says he went home after removing the blockade to have a nap, and that by the time he got back, the tractors had arrived.

Lynch says he doesn't know who the tractors belong to.

"I don't know where they came from. It was bizarre," he said.

What appears to be a tractor with no license plate is shown driving up the roadway to the mine in a video posted by Unifor Canada Saturday.
